How can I set a specific bin size?

I want to do horizontal binning of .tif images. I previously was doing this by setting the number of breakpoints I wanted to create binning to collect data from an image. However, instead of setting a number of breakpoints in which the bin size is dependent, I want to set a certain bin size due tho the number of pixels in each size. Only issue is, I'm not quite sure where to start. Any suggestions?

How are you doing the horizontal binning? Which function are you calling?

breakpoints = 1 : FixedBinSize : sz(2)-FixedBinSize+1;

%...
for xvalues = 1:length(breakpoints)-1
    im = qudrant(:, breakpoints(xvalues):breakpoints(xvalues+1)-1, :);
    %...
end

Note that with a fixed bin size you have the problem that the image might not be an exact multiple of the bin size. The above code deals with the situation by not generating any partial image. You need to decide whether in your situation you want to instead

• use a final smaller image
• pad the boundary

If you want to use a final smaller image then after setting

breakpoints = 1 : FixedBinSize : sz(2)-FixedBinSize+1;

add in

if breakpoints(end) ~= sz(2); breakpoints(end+1) = sz(2); end
